EOS, Novi, Mich., will exhibit recently developed metal and plastic materials – EOS NickelAlloy IN625, PrimePart FR (PA 2241 FR), and PrimePart ST (PEBA) – for specialized industrial uses at RAPID 2011.
EOS NickelAlloy IN625. Material properties such as high tensile strength, good processability, and good corrosion resistance make this super alloy suited for use in aerospace, chemical, motor sport, and marine industry applications.
PrimePart FR (PA 2241 FR). This material is flame-retardant and particularly suitable for aerospace. Based on PA 12 polyamide, it has an 11 percent elongation at break, significantly higher than its predecessor, PA 2210FR. It also has a lower refresh rate (ratio of new to re-used powder), offering cost savings and environmental benefits.
PrimePart ST (PEBA). This flexible elastomeric polyether block amide has unique customizable mechanical properties. Different laser-exposure strategies can be used to create either hard or soft components. PrimePart ST has a good refresh rate, making it an environmentally favorable alternative to other flexible materials for laser sintering. With this plastic, previously impossible laser-sintered applications, such as flexible fasteners, seals, or buffers, are possible.
